电动可变变速器(EVT)状态包括操作,其中经由输入构件10、第一扭矩机20和第二扭矩机25的机械动力输入被传递至驱动构件68,且基于输入构件10和第一扭矩机20的转速确定输出构件65的转速。因此,经由输入构件10的机械动力输入可由来自第一扭矩机20的机械动力补充,以将输出动力提供至驱动构件68,或经由输入构件10的机械动力输入可被分流,以将机械动力供应至第一扭矩机20,并将输出动力提供至驱动构件68。

输出-分流变速器状态为变速器100在其中以低效传动比进行操作的EVT状态,其中最终驱动比由第二扭矩机25的转速确定。从,例如,内燃机输入至输入构件10的机械动力可连同来自第一扭矩机20的动力一起被传递至输出构件65。来自第二扭矩机20的机械动力可在输出构件65与第一扭矩机20之间分流。这通过将输入离合器40控制在第一状态(C)中、将输出离合器50控制至第二状态(R)以及将最终离合器62控制至第二状态(2)得以实现。
